Role of Pigmentation in Zooplankton of Alpine Lakes
Wyoming is unique, with short summers, long cold winters, strong winds and high UV radiation at high elevation. Zooplankton are small animals persisting in the water column of alpine lakes and play an important role in aquatic food webs. To cope with high UV stress zooplankton concentrate large amounts of photoprotective pigments that act as antioxidants, neutralizing dangerous free radicals within body tissues. Zooplankton in alpine lakes display aesthetic colors from almost clear to pink and light orange to deep red depending on pigment type and concentration. Pigmentation is plastic, meaning ...
